## NAME
    [Crypt::PasswdMD5](https://www.chedong.com/phpMan.php/perldoc/Crypt%3A%3APasswdMD5/markdown) - Provide interoperable MD5-based crypt() functions

## SYNOPSIS
            use strict;
            use warnings;

            use [Crypt::PasswdMD5](https://www.chedong.com/phpMan.php/perldoc/Crypt%3A%3APasswdMD5/markdown);

            my($password)       = 'seekrit';
            my($salt)           = 'pepperoni';
            my($unix_crypted)   = unix_md5_crypt($password, $salt);
            my($apache_crypted) = apache_md5_crypt($password, $salt);

            Or:

            use strict;
            use warnings;

            use [Crypt::PasswdMD5](https://www.chedong.com/phpMan.php/perldoc/Crypt%3A%3APasswdMD5/markdown) 'random_md5_salt';

            my($length) = 7;
            my($salt_1) = random_md5_salt($length);
            my($salt_2) = random_md5_salt(); # Default to $length == 8.

## DESCRIPTION
    "apache_md5_crypt()" provides a function compatible with Apache's ".htpasswd" files. This was
    contributed by Bryan Hart <<bryan@eai.com>>. This function is exported by default.

    The "unix_md5_crypt()" provides a crypt()-compatible interface to the rather new MD5-based
### crypt
    FreeBSD 2.2.[56]-RELEASE. This function is also exported by default.

    For both functions, if a salt value is not supplied, a random salt will be generated, using the
    function random_md5_salt(). This function is not exported by default.

## LICENSE AND WARRANTY

    This code and all accompanying software can be used freely under the same terms as Perl itself.

## METHODS
  apache_md5_crypt($password, $salt)
    This sets a magic variable, and then passes all the calling parameters to
    "unix_md5_crypt($password, $salt)".

    Returns an encrypted version of the given password.

    Basically, it's a very poor choice for anything other than password authentication.

  random_md5_salt([$length])
    Here, [] indicate an optional parameter.

    Returns a random salt of the given length.

    The maximum length is 8.

    If $length is omitted, it defaults to 8.

  unix_md5_crypt($password, $salt)
    Returns an encrypted version of the given password.

    Basically, it's a very poor choice for anything other than password authentication.
